They're sky-mariners, boyanced upon the air currents; paying attention to the clouds is what they do.
They'd pay attention to a dragon, regardless of if it's made of ice or no.
-Couple that with the fact we're made of magic ice, and I'd say if we keep pretty high above them we'll be harder to see without our mist.
Aheheh. Ignoring how very little ice is like that, we've got bones in the middle. And have you never heard of camoflage?
And darn, I was hoping you'd argue about the relative suspiciousness of stalker-clouds vs stalker-dragons.
Well, it's not that I think stalker clouds are inconspicuous, it's that they're pretty mundane compared to dragons.
Besides, clouds move all the time. They're not mountains. We might be a little out of the ordinary, but if we don't do anything stupidly obvious or obviously stupid it'll work better than being a
dragon, made of ice, with bones in the middle which may or may not be visible.
